Definitely not. Subway is for everyone to commute comfortably. Sitting on someone's lap like that can make others feel uncomfortable and it also goes against basic public behavior rules. There should be personal space boundaries in public areas.
It depends on the situation. If it's a small child sitting on a parent or a close family member's lap, it's usually appropriate as it's a way of providing comfort and safety in a crowded bus. However, if it's an adult sitting on another adult's lap in a non - emergency situation, it can be seen as inappropriate in most cultures.
Yes, it is generally appropriate in a non - sexual, affectionate way. Fathers often have a close bond with their sons, and sitting on a lap can be a sign of love and closeness, like when reading a book together or just having a cuddle.
Yes, it's possible. There are many different interpretations in fanfiction. Maybe in this particular fanfic, the 'forced' part isn't as sinister as it sounds. It could be that a magical spell has gone wrong and Harry Potter ends up on someone's lap as a result, and the story then focuses on how they get out of this awkward situation in a light - hearted and family - friendly manner.
It is generally not appropriate for a married person to sit on someone else's lap. It can send the wrong signals and make others uncomfortable, as it violates the boundaries of a committed relationship.
It depends on the nature of the friendship. In some very close and platonic friendships, it might be a moment of innocent fun or comfort. For example, if two friends are joking around and one briefly sits on the other's lap in a light - hearted way. But in general, it can also make people feel uncomfortable as it crosses personal space boundaries.
In some cases, it can be appropriate. If they are in a situation where there are no other options due to space constraints and it's a family - only environment, it may be okay. For example, if they are in a small camper van and all the seats are occupied with necessary items.
Well, generally speaking, it's not proper. We should uphold certain social and family norms. Mom and son are family members, but this kind of overly intimate physical contact like sitting on the lap might make both of them feel uncomfortable in a way, and it also doesn't conform to the common sense of propriety in family relationships. There could be other options like sharing a seat cushion or rearranging the seating in the vehicle to make the long drive more comfortable without this kind of inappropriate behavior.
One interpretation could be a child sitting in a parent's lap, which is a sign of affection and closeness within a family. For example, a small kid might sit in their mother's lap while listening to a bedtime story.
It's usually not a good idea. A friendship is based on mutual respect and understanding. Physical contact should be within the limits of propriety. Sitting on a lap can be misconstrued as having romantic or sexual undertones, even if that's not the intention. Friends should communicate clearly about what kind of physical contact is acceptable to both parties to avoid any misunderstandings or discomfort.
Well, it could be that the man is an old wizard who has some important information to pass on to Harry. In order to do this in a very old - fashioned and perhaps superstitious way, he asks Harry to sit on his lap. Harry is initially reluctant but then realizes the importance of the information and complies. The story could then be about how Harry uses this new knowledge to solve a mystery at Hogwarts.
